HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 472, 307 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 472, 307 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 472, 307 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 472, 307 is 1.
HCF(472, 307) = 1
HCF of 472, 307 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 472, 307 is 1.
Highest Common Factor of 472,307 is 1
Step 1: Since 472 > 307, we apply the division lemma to 472 and 307, to get
472 = 307 x 1 + 165
Step 2: Since the reminder 307 ≠ 0, we apply division lemma to 165 and 307, to get
307 = 165 x 1 + 142
Step 3: We consider the new divisor 165 and the new remainder 142, and apply the division lemma to get
165 = 142 x 1 + 23
We consider the new divisor 142 and the new remainder 23,and apply the division lemma to get
142 = 23 x 6 + 4
We consider the new divisor 23 and the new remainder 4,and apply the division lemma to get
23 = 4 x 5 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 472 and 307 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(23,4) = HCF(142,23) = HCF(165,142) = HCF(307,165) = HCF(472,307) .
